NASA Space Happenings (4 Comments) (link)

Just for a bit of a change, here is some various pieces of news from NASA about things that they are involved with and news about their projects.

NASA is opening applications for new astronauts as part of their class of 2009. NASA is accepting applications for the 2009 Astronaut Candidate Class. Those selected could fly to space for long-duration stays on the International Space Station and missions to the moon. "We look forward to gathering applications and then being able to select from the largest pool possible," said Ellen Ochoa, NASA's chief of Flight Crew Operations at the Johnson Space Center. "Continuing our impressive record in successfully carrying out challenging human spaceflight missions depends on maintaining a talented and diverse astronaut corps." To be considered, a bachelor's degree in engineering, science or math and three years of relevant professional experience are required. Typically, successful applicants have significant qualifications in engineering or science, or extensive experience flying high-performance jet aircraft.

They are also doing some interesing imaging projects including partnering with the Internet Archive. NASA and Internet Archive of San Francisco are partnering to scan, archive and manage the agency's vast collection of photographs, historic film and video. The imagery will be available through the Internet and free to the public, historians, scholars, students, and researchers. Currently, NASA has more than 20 major imagery collections online. With this partnership, those collections will be made available through a single, searchable "one-stop-shop" archive of NASA imagery.

Google Moon is getting some more interactive content from NASA. New higher-resolution lunar imagery and maps that include NASA multimedia content now are available on the Google Moon Web site. Updates include new content from the Apollo missions, including dozens of embedded panoramic images, links to audio clips and videos, and descriptions of the astronauts' activities during the missions. The new content is overlaid on updated, higher-resolution lunar maps. Also added are detailed charts of different regions of the moon suitable for use by anyone simulating a lunar mission.

NASA's Mars rovers have managed to survive severe dust storms threatening their solar power source. Two months after sky-darkening dust from severe storms nearly killed NASA's Mars exploration rovers, the solar-powered robots are awake and ready to continue their mission. Opportunity's planned descent into the giant Victoria Crater was delayed, but now the rover is preparing to drive into the half-mile diameter crater as early as Sept. 11. Spirit, Opportunity's rover twin, also survived the global dust storm. The rovers are 43 months into missions originally planned to last three months. On Sept. 5, Spirit climbed onto its long-term destination called Home Plate, a plateau of layered bedrock bearing clues to an explosive mixture of lava and water. "These rovers are tough. They faced dusty winds, power starvation and other challenges -- and survived.

Amazingly, the Voyager spacecraft are still sending back information even after 30 years of flight. Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched on Sept. 5, 1977. They continue to return information from distances more than three times farther away than Pluto. "The Voyager mission is a legend in the annals of space exploration. It opened our eyes to the scientific richness of the outer solar system, and it has pioneered the deepest exploration of the sun's domain ever conducted," said Alan Stern, associate administrator for NASA's Science Mission Directorate, Washington. "It's a testament to Voyager's designers, builders and operators that both spacecraft continue to deliver important findings more than 25 years after their primary mission to Jupiter and Saturn concluded."

They are also working on super heat resistant microprocessors. In the past, integrated circuit chips could not withstand more than a few hours of high temperatures before degrading or failing. This chip exceeded 1,700 hours of continuous operation at 500 degrees Celsius - a breakthrough that represents a 100-fold increase in what has previously been achieved. The new silicon carbide differential amplifier integrated circuit chip may provide benefits to anything requiring long-lasting electronic circuits in very hot environments.
